摘要：
Viscosity behavior of cellulose acetate(CA) and its blends in different solvents has been studied. The pervaporation behavior of their membranes from the corresponding solvents has been measured for separating methanol/methyl ter-butyl ether (MeOH/MTBE) mixture. It was found that the permeation flux (J) of the membranes is reciprocal to the viscosity slope coefficient (b) in its dilute solutions.
